Summit Racing® SFI-Approved Flexplates SUM-G100SFI

Yes, if your 383 is internally balanced.

COREY A from MI answered on November 17, 2017

Hello , this flexplate is for an internally balanced motor . Most 383 stroker motors are externally balanced . You would need a flexplate for an externally balanced motor to work with your motor combination .

DANNEY from CA answered on November 04, 2017

It works on my 77 Vette. The trick is to have the engine balanced internally. If it is a one piece seal,use a adapter to a two piece seal
It

RICHARD from IN answered on November 17, 2017

Yes it will. Stroke has nothing to do with fittment. It is still a basic 350 base crank on the hub.

ANDY from GA answered on November 05, 2017

Yes. I've used it on a internally balanced 540 bbc and 383 stroker with a Turbo 350

ROLAND from LA answered on November 11, 2017

It will work if you have a stroker kit who is internal balanced and have a starter who is made for 168-tooth flexplate.

LEIF from Sweden answered on November 13, 2017

If you have a internally balanced crank it.will work.

CARL from ID answered on October 30, 2017

As long as you have a 10.5 inch torque converter patern and a standard chevy crankshaft bolt pattern it should fit a th350, i installed mine in a th400. Be sure to cross reference your conveter size and bell housing on your 350.

GLENN A from IL answered on October 30, 2017

If you have an internally balanced crank. Stock 400 cranks are externally balanced. After market cranks can be internally balanced with a 3.75 stroke.

MARK from NC answered on November 03, 2017

Nerds to be internal balanced

STEVEN from IN answered on November 02, 2017

I believe this flexplate is for a 350 gen 1 engine. I believe your 383 will have a 400 crankshaft, balancer, and will require a 400 flexpate.

KEN from CO answered on November 15, 2017

Yes this will work with a 383 stroker. All a 383 is , is a 350 Chevy with a 400 crank. All GM trans will bolt up ie tubto 350/400/700R4/200. Good luck

ROBERT K from MN answered on November 05, 2017

Yes, if it's a stock stroke crankshaft, it will work. I have one on my V8 S10 355 w/700R4. Solved my starter issues. Can be used with straight or offset bolt pattern starters. I use a straight bolt Tuff Stuff starter.

GENE from PA answered on October 14, 2017

You need the externally balanced one

PATRICK from MN answered on October 15, 2017

Only if the engine has been internally balanced.

LONNIE from CA answered on October 05, 2017

NO 454 HAS A BALANCE ON FLYWHEEL. THIS DOES NOT

RICHARD from PA answered on October 21, 2017

I think so

MARK from NC answered on October 03, 2017

the flexplate to torque converter I think is pretty much universal, flexplate to crankshaft is the important match.

GARY from CA answered on October 19, 2017

This Flexplate works with internal balance motor a 454 is external get external will work a 4L80 is no more than a Turbo 400 with overdrive

KIM from NC answered on October 20, 2017

No will not work.

MITCHELL from CO answered on October 21, 2017

Yes you just need to now is it a 1piece or 2 piece rear main and if it is internal or external balance external needs a weight on it and internal has no weight

KELLY from AR answered on October 16, 2017

GREGORY from CA answered on October 18, 2017

No, this flex plate is internal balance, 454 is external balance.

JERRY from CA answered on October 18, 2017

No,big block is ext balance

GEORGE F from TX answered on October 16, 2017

No , you will need an external balanced flywheel unless you have your crankshaft modified to become internal balanced. This is usually done by having Mallory metal installed

DANNEY from CA answered on October 05, 2017

No it will not work for 454. This flywheel is for internal balance. 454 is external balanced.
